Transmission line Subwoofers?


Does anyone know of any commercially available subs that use a transmission line design?

There are a bunch of DIY subwoofer designs on the web using TL enclosures, including one that (I believe) Teres Audio will build for you. If memory serves, Wisdom Audio (used to?) sells a finished product, as well. Not a lot of choices out there AFAIK.
